We have all probably experienced how good it feels to clean fish slime and the stink of fish off our hands after handling them. Osprey, which eat fish almost exclusively, have developed a unique method for dealing with the problem. They will glide low over water, lower their legs, and drag them for a surprising distance until their flight is close to stalling. Then, they will pull out, get their speed up, and do the same thing perhaps three or four times until their extremities are clean. Those of you who have swished your hands quickly through the water at the side of a lake to clean off slime know exactly how effective this can be.
